Abstract: The surveys of species composition and distribution of ichthyoplankton were carried out in Dongshan Bay of Fujian during spring (May, 2008) and summer (August, 2008). The compositions of fish eggs, larvae and juveniles, as well as abundance of temporal-spatial distribution in Dongshan Bay were studied. The results showed that there were 24 species of fish eggs, larvae and juveniles had been indentified, of which 16 were identified to species, 4 to genus, 4 to family and 2 unidentified. The fish was active in reproduction during spring and summer, while there were plenty eggs and larvae in the bay. The number of fish eggs, larvae and juveniles were mainly consists of migratory economic species, such as Etrumeus teres, Sardinella aurita, Sardinella zunasi, Sillago japonica and Argyrosomus argentatus. Intensive areas of fish eggs in spring was in coastal water of middle and west of Dongshan Island, while in Tayu Lslet near the estuary in summer. In compare with other gulfs in Fujian, Dongshan Bay is one of the most important spawning grounds for migratory economic fish.
